Ive been having troubles with my pc since i first got it, Nearly everything in it has had to be replaced and im still having troubles. Heres my setup: Mobo = Asus A8N Premium Graphics = Nvidia Gforce 6800GS CPU = Amd 64 3200+ Dno what make my HD's are But ones a 30 and ones a 20 GB and i got 1GB of 2x Corsair 512mb pc3200 DDR1. All was working fine for a while after i had my Motherboard replaced because it was faulty then one day it just crashed and wouldn't boot up for an hour or so. So i left it thinking it had overheated and came back to it to start it up, It started booting up fine until it got to the Windows logo, where the bar travels across the screen, Froze and restarted, It wouldnt stop. Now there is a few possabilities, Either the graphics card has been fried in the past, because it was running way to hot and i had to fit a pci slot fan next to it to cool it, The cpu chip is fried because the cpu fan is faulty and i need it replacing, The PSU cant handle the setup as its quite old asin over a year and only 400W Or; The hard drive has failed (last time i took it in the shop they said it had a corrupt section but it wouldnt effect windows or anything at that time but it may have goten worse). If any of you have any idea whats wrong could you please post as i am in need of knowing so as i can take it in the shop and get it fixed rather than getting them to spend time and me to spend money finding out what it is.
